President Biden pulled off a secret trip to the war-torn country of Ukraine on Monday to meet with Ukrainian President Volodymyr Zelensky. How this trip came together is worth reading:

How much planning went into the visit?: *Months* of secret planning with a small number of officials involved.

When was the trip confirmed?: Biden made the final call on Friday. 

Was Russia informed of the trip?: Yes, Russia was alerted but only a few hours before Biden’s arrival. 

How did Biden get to Poland?: Biden left from Joint Base Andrews around 4 a.m. on Sunday with a few advisers. The plane stopped in Germany to refuel then landed in Poland. The New York Times notes that the shades were left down. Biden then took a 10-hour train from Poland to Ukraine. 

Did any press travel with Biden?: Yes, The Wall Street Journal’s Sabrina Siddiqui and The Associated Press’s Evan Vucci were told about the trip on Friday and sworn to secrecy. They were even sent an email with the subject line, “Arrival instructions for the golf tourney,” for the logistics.

The New York Times’s Peter Baker and Michael D. Shear have some fascinating details of how the trip was kept secret. 

Excerpt that puts the significance into context: “Never in Mr. Biden’s lifetime had a president ventured into a war zone that was not under the control of American forces, much less on a relatively slow-moving locomotive that would take nine and a half hours to reach its destination. During that time, he was potentially exposed to circumstances beyond the control of the hypervigilant security phalanx that normally seeks to shield a commander in chief from every conceivable physical danger and minimize his time outside a hardened shelter.”

“How do you sneak a US president into a warzone without anyone noticing?”

Russian President Vladimir Putin pulled out of the only remaining nuclear arms control treaty with the U.S. this morning. 

What treaty?: The New START treaty 

Plus: “Speaking in his state-of-the-nation address, Putin also said that Russia should stand ready to resume nuclear weapons tests if the U.S. does so, a move that would end a global ban on nuclear weapons tests in place since Cold War times.”  

Why this is important: The Associated Press’s Vladimir Isachenkov points out that this move “sharply [ups] the ante amid tensions with Washington over the fighting in Ukraine.”

President Biden just delivered remarks from the stunning gardens of Warsaw's Royal Castle during his planned Poland trip following his surprise visit to Ukraine.

From Biden: "President Putin is confronted with something today that he didn't think was possible a year ago. The democracies of the world have grown stronger. Not weaker. But the autocrats in the world have gotten weaker, not stronger." (Quote from Bloomberg’s Jordan Fabian) 

Another quote from Biden: "Kyiv stands strong. Kyiv stands tall and most important, it stands free … The world would not look the other way." (Quote from CNN’s Jeff Zeleny)

From CNN’s Kevin Liptak 

Rep. David Cicilline (D-R.I.) announced this morning that he will step down from Congress in June. 

Why?: To become the president and CEO of the Rhode Island Foundation. 

So, what happens to his seat?: There will be a special election for his seat, though The Boston Globe points out that it cannot be scheduled until Cicilline officially resigns.

Speaker Kevin McCarthy (R-Calif.) gave Fox News host Tucker Carlson and his team access to 41,000 hours of surveillance footage from the Jan. 6, 2021, U.S. Capitol riot. 

Keep in mind: The Hill’s Dominick Mastrangelo pointed out that Carlson has questioned the circumstances around the attack.

Axios’s Mike Allen first reported the news. Read Axios’s initial report 

“It’s hard to overstate the potential security risks if this material were to be used irresponsibly,” Johnson said in a statement. “If Speaker McCarthy has indeed granted Tucker Carlson — a Fox host who routinely spreads misinformation and [Russian President Vladimir] Putin’s poisonous propaganda — and his producers access to this sensitive footage, he owes the American people an explanation of why he has done so and what steps he has taken to address the significant security concerns at stake.”

“Three key figures connected to Donald Trump are at the intersection of two accelerating Justice Department probes seen as the most viable pathways for a prosecution of the former president.”  

How so: “Special counsel Jack Smith is overseeing what began as two entirely separate cases: the mishandling of classified records at Mar-a-Lago and the effort to influence the 2020 election that culminated in the Jan. 6 attack on the Capitol. Several Trump World figures straddle both events, providing prosecutors with what experts say is a potent opportunity to advance both investigations.”  

Who?: Alex Cannon, a longtime Trump Organization employee; Christina Bobb, a lawyer for Trump’s 2024 campaign; and Kash Patel, who served as chief of staff to the acting secretary of Defense at the Pentagon. 

^ Keep in mind: “It’s unclear whether any of the trio faces significant legal exposure, but their unique positions could be valuable for Smith.”
